support electrically heated sad irons or similar implements when thesame are not in use.

cOne of the objects of my inventionl is to provide a device. oftheabove-indicated character whichshall be simple, compact and durable inconstruction, inexpensive to assemble and manufacture, and particularlyadapted to prevent the conductionor transmission of lheat from theheated body to the surface upon which the stand rests.

ccording to my invention, l provide a supporting structure of thisgeneral class which comprises a plurality of punched or pressed sheetmetal parts which may be formed at relatively small expense, and may bereadily assembled and united in such manner as to ed'e'ctively performtheir intended functions and also provide a stand which shall beparticularly strong and adapted to withstand careless and rough usage.

lin the accompanying drawing, Figure 1 1s a side elevational view of asupporting structure embodying my invention, and including anelectrically `heated sad iron in position thereon, and Fig. 2 is a planview of the device shown in Fig. l with the sad iron and a portion ofsaid device removed for the sake of clearness. Figs. 3 and I are l viewsrespectively similar to Figs. l and 2 of a modified' form ofmy-invention, a portion of Fig. 3 being shown in section.

Referring particularly to Figs. 1 and 2, a

heated body l, which is shown for illus-A trative purposes as anelectrically heated sad iron, but` which may constitute any other heatedimplement, rests upon a supporting structure or stand 2. rlllhe stand 2comprises a plurality of plates' 3, 4 and 5 which are preferablyconstructed of sheet metal and which are substantially 'of the sameshape-or contour as the sad iron l, or

other body which the stand 2 is adapted to support. I

The plate 3 constitutes a supporting plate for the sad iron l, and itsouter side edges 6 are disposed at substantially right angles to themain portion thereof `to form an upwardly projecting outer flange whichis adapted to maintain the sad iron in position: A portion 7 at the heelof the plate 3 1s slightly inclined with respect to the main body of theplate in order to assist in slidmg the device l into its proper positionupon the stand in case it is hastilyl or carelessly placed thereon. Aplurality of downwardly projecting integral spherically curved portions8 are also provided upon the plate 3, one of which is convenientlylocated near the toe of the plate while the other portions are locatedat the heel thereof. Obviously, the plate 3 may be constructed andformed in any well known and desired manner, although I ind' itpreferable to punch the same out of a sheet metal blank and to press thespherically curved projecting portion 8 therein in accordance with wellknown practice. ln this manner, the necessary work may be accomplishedwith facility and comparatively small expense, and the plates thusproduced are particularly adapted for the purposes intended.

Plate 5 constitutesa supporting base, and

although shown somewhat larger in size than the plate 3, to accommodatea larger iron, it is otherwise similar and is constructed in the samemanner as that already described. r)The plate 5 embodies downwardlyprojecting outer flanges 6a, an inclined end ange 7a, and a plurality ofupwardly projecting integral spherically curved portions 8a whichare'correspondingly located with respect to the spherically curvedportions 8 of the upper plate 3.

rThe intermediate plate 4, which constitutes a baffle or aheat-radiating plate that may or may not be used, rests upon the up,-wardly projecting portions 8a, and, disposed upon the plate 4;,'is theupper supporting plate 3 having its downwardly projecting integralportions 8 located directly abovethe projecting portions Sain suchmanner that the several plates are in contact or engagement only atthree points, which, by reason of the shape of the projecting portions 8and 8a, are `of comparatively small area.

order to secure vthe several parts rigidly to- Veo gether to form astrong and unitary structure, a plurality of rivets 9, or othersuitablemeans, are employed, said rivets 9 or other means being locatedsubstantially at the points of engagement.

lIt should, of course, be understood that the plates 3, 4 and 5 may ormay not be of substantially the same size, but, in many cases, it isdesirable to make them of somewhat different sizes, as shown in thedrawing, in order that the stand may be reversible, whereby it isadapted toI accommodate different sizesv of sad ironsor otherimplements.

When the stand is used for supporting a heated body, such as theelectrically heated sad iron 1, inappreciable amounts of heat aretransmitted to the supporting base plate 5 by reason of the fact that aminimum number of engaging points are provided, and said points are ofcomparatively small area, so that very little heat is transmittedtherethrough. Furthermore, the intermediate baiiie or radiating platev 4serves to obstruct the direct downward radiation of heat from the heatedbody 1 and also tends to radiate such heat freely into the atmosphere.Attention is also directed to the fact that the base plate 5 is adaptedtoengage any vconvenient supporting surface (not shown) only at thebottom edges of the side flanges 6e.' Thus an air space is providedbeneath the base plate 5 which assists in. cooling the same andpreventing undesirable heating of the supporting surface. Moreover, avery small portion of the base plate 5 is in'actual engagement with thesupporting surface, and a large portion of the plate 'is exposed forradiation so that the amount of *heat actually transmitted to thevsupporting surface is comparatively negligible.

Referring now to Figs. 3 and 4 of the accompanying drawing, anelectrically heated body 1 is supported 'upon a stand or structure 2which comprises an upper supporting plate 3 and a lower base plate 5which are similar in construction to the plates 3 and. 5 shown anddescribed with reference to Figs. 1 and 2, and which are disposed theone upon the other and secured together in a manner similar to thatwhich has already been set forth, and on account of this similarity -instructure and assemblage, no further detailed description thereof isdeemed necessary. It should be noted, however, that the upper plate 3 isprovided with a plurality of upwardly projecting spherically curvedportions 10, one of which is disposed at the toe of the stand 2, whilethe remaining projections are svmmetrically located at the heel thereof.The projections 10, just referred to, serve to support the heated body 1upon three points of very small area so that the direct conduction ofheat to the plate 3 is very small. The plate 5 is also provided withsimilarly disposed downwardly projecting spherically curved portions 10which are adapted to serve the purpose of supporting a heated body 1when the stand 2 is reversed in position so that the plate 5 constitutesthe upper supporting plate.

In many cases, it may be found unnecessary to provide an intermediatebaiiic or radiating plate such Aas is shown in Figs. 1 and 2, and nosuch plate is employed in the supporting structure shown in Figs. 3 and4, the upper and lower plates 3 and 5, respectively, being in directintimate engagement through their oppositely projecting portions 8 and8a. t will, of course, be understood that, if desired, an intermediateplate such as is shown in Figs. 1 and 2, may be inserted between theupper and lower plates 3 and 5 of the supporting stand shown in Figs. 3and 4, or it may be found desirable to construct the supporting stand inaccordance with Figs. 1 and 2 but with the intermediate radiating plateomitted.

Obviously, many other variations and modifications in the structuraldetails and arrangement and location of parts may be effected withoutdeparting from the spirit and scope of my invention, and I desire thatonly such limitations shall be imposed as are indicated in the appendedclaims.

I claim as my invention:

1. A stand for supporting heated bodies comprising a plurality of plateshavingsubstantially plane surfaces and having correspondingly disposedintegral curved portions that severally coperate, 'the one with theother, in pairs, and means for securing said plates together.

2. A stand for supporting heated bodies comprising a plurality ofsimilar plates having substantially plane surfaces and havingcorrespondingly disposed integral curved portions that project laterallybeyond the adjacent surfaces of the plates, into proximity to eachother, and an intermediate plate interposed between the curved portionsof said first mentioned plates.

3. A sad iron stand comprising a sheet metal base plate having aplurality of upwardly projecting integral portions and a substantiallyplane portion, a second sheet metal plate resting thereon, a third sheetmetal plate having correspondingly located downwardly projectingintegral portions adaptedto rest upon said second plate directly abovethe first-mentioned integral portions, and means for securing said partstogether at their points of contact.

4. A supporting'structure for heated bodies comprising a plurality ofsheet metal plates having correspondingly and oppometier sitely disposedpressed portions and an intermediate plate adapted to engage saidpressed portions at a plurality of points, and means for rigidly unitingsaid parts at the points of engagement. l

5. A -sad iron stand comprising a sheet metal base plate havingdownwardly projecting edges and a plurality of upwardly projectingintegral pressed portions, a radiating plate resting on said portions,and a sheet metal supporting plate having oorrespondingly locateddownwardly projecting portions adapted to rest upon said radiatingplate, and a plurality of rivets for uniting said parts together attheir engaging por- [15 tions.
